... V838 Mon is a member of a new class of eruptive variables which appear as a peculiar novae having late K-M type spectra in their outburst. Before its outburst, it was a wide binary system of B3V type stars. ... The B3V companion was seen in the outburst in the UV spectrum taken with HST (Rauch et al., ... In the latest spectra, the light of B3V companion was predominating in the short-wave photometric bands. ... CCD blue frames of V838 Mon before the eclipse (left) and in the eclipse (right). ...

... Like the night sky on the Earth, the martian sky hosts a plethora of astronomical phenomena occurring around the clock in a neverending space opera played out for the benefit of robotic and future human observers alike. ... Moons . Mars has two moons, Phobos and Deimos . ... Under the same conditions, Deimos would be as bright as -5, somewhat brighter than the planet Venus appears in Earth's sky. ... The moons are also eclipsed by Mars itself (a situation analogous to lunar eclipses at the Earth). ...

Astronotes Armagh Planetarium's Stellar Blog! ... Earth Satellites . ... According to Velikovsky, about 4000 years ago a giant volcano on Jupiter erupted and spewed a vast glob of debris into space, leaving the Great Red Spot behind as a permanent scar. The red hot lump ejected from Jupiter (referred to as a comet by Velikovsky) wandered into the inner Solar System, repeatedly crossing the Earth?s orbit and in fact often passing close to our helpless planet in the following millennia. ...

XMM-Newton Science Analysis System . ... A different approach is done via the setting withctisrcpos =Y: all event energy corrections do not use the actual RAWY coordinate but the corresponding RAWY location of the source ( SRCPOS ) as determined by the task epframes (either automatically or via setting withsrccoords =Y). ... The task epchain may be used with the setting ccds =4 withctisrcpos =Y to process only the CCD 4 where usually the bright source is located that causes the Out-of-Time events. ...
